WINDOW-SCREEN.

Specification of Letters Patent. Patented March 23, 1909. Application filed. August 15, 1907. Serial No. 388,667.

To all whom it may. concern.

Beit known that I, Gnovn Areas, a citizen of the United States of America, residing at Athens, in the county of Athens and State of Ohio,have invented new and useful Improvements in Window-Screens, of which the following is a specification.

' ,tac-hment from said screen so that the win-' This invention relates to window screens, and one of the princi al objects of the same is torovide a-screen tted into a recessinthe win ow framing and to provide the lower sash withmeans for attachment to and dedow maybe raised and lowered-without the sash or with the same as required.

Another object of the invention is to pro- 'vide a slidin window screen and a splin actuated hoo for en aging said screen, sai hook being connected to the lower cross bar of' the-lower window sash, and means for operating said hook to engage the screen or to disengage the same at wil These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which:

Figure 1 is" an elevation and partial section of the inside of a window frame and sash,

and showing the Window screen in a recess numeral 1 designates the window frame, 2

is the upper sash, and 3 the lower sash. Underneath the window sill 4,- a recess 5 is provided, and a Window screen 6 is adapted to slide in said recess. Suitable guide strips 7 upon opposite sides of the screen 6 are utilized to insure a smooth action of the window screen. In the upper frame bar of the screen 6 a recess 8 is formed and a cross pin Qspans the recess. I

Connectedto the lower bar 10'of the lower sash is a pivoted hook comprising a shanlt 11, a thumb hold 12, and a depending hook 13, said shank being passed through the. bar 10 and said hook bemg seated ina recess 14 with a spring 15' bearing a ainst the wall of the recess 5 to hold the bifi 16 into engagement with the pin 9.

From the foregoing it will be obvious that the lower sash may be raised and lowered whenever re uired without attachment to the screen 6, y tuning the thumb hold or sash lift 12, and lifting thesash by means of this hold. Whenever it is required to raise the screen 6, the bill 16 of the hook is engaged with the pin 9, and the screen 6 is raised with the sash 3 by means of the sash lift 12.

My invention'is of simple construction, can be applied to any window with very slight alteration, is'strong, durable and eflicient in use, can be manufactured at slight cost, and owing to the head a which fits a groove in the lowerbar of sash 3, provides eflicient meansfor preventing the entrance'of snow or ice or rain.

The bill 16 of the hook is rovided with a curved lower face 16, and yprovision of j the spring 15 it will be seen that the said curved face 16 lies always in such position that it can be engaged with the pin 9. As-

suming the hook 13 to be disengaged from the pin 9 when the lower sash 3 is raised and it is desired to use the screen, it will appear that upon lowering. the said sash 3 the hook 13 by reason of the curved face 16? of the bill 16 will be automatically engaged with the pin 9.

. Having thus described the invention, what I claim is:

A window frame having vertically sliding upper and lower sashes, the lowersash having a recess formed in the underside of its bottom bar, a slidin screen disposed beneath the lower sash, sai sliding screen having a recess formed in the up or bar thereof and.

disposed directl beneat the recess formed in the lower sas a pin located in the recess Q Y i i erases formed in the upper bar of the screen, a hook said hook in such position that it will engage 1e ivotall mounted-in the recess formed'in the the in automatically when the lower sash is ottom arof the lower'sash and provided at at t e downward limit of its movement.

its lower end with a hill having a curved In testimony whereof, I afiix my signature 5 lower face, and a sprinilocated in the recess in presence of two witnesses.
